Can be solved using the concept of magic squares too..

Many varieties for A, B, C, D, E, F, G, H, I are possible but only 999 was found for J J J.

J CANT BE 1,2,3,4,5 BCOZ MIN VALUE OF A+D+EIS 1+2+3=6 J IS SUCH A NUMBER WHICH CAN BE EXPRESSED AS A SUM OF 3 NOS IN 3 DISTINCT WAYS SO J=9

$\quad \quad 5\quad 6\quad 8\\ +\quad 3\quad 2\quad 7\\ \quad \quad 1\quad 0\quad 4\\ \quad \quad \boxed { 9\quad 9\quad 9 }$
